合成路线1
该中间体在本合成路线中的序号:(VII)The alkylation of theobromine (I) with undecenyl mesylate (II) in the presence of NaH in DMSO afforded the 1-undecenyl xanthine (III). Dihydroxylation of the terminal double bond of (III) by means of N-methylmorpholine-N-oxide and a catalytic amount of potassium osmate gave diol (IV), which was further converted to bromo acetate (V) by treatment with a solution of HBr in AcOH. Methanolysis of the bromoester (V) with concomitant cyclization gave rise to epoxide (VI). Finally, epoxide opening upon heating with dodecylamine (VII) furnished the target amino alcohol.

合成路线2
该中间体在本合成路线中的序号:Bromination of ethyl 4-hydroxybenzoate (I) by means of N-bromosuccinimide and HBF4.Et2O produced ethyl 3-bromo-4-hydroxybenzoate (II), which was further iodinated to (III) employing I2 and K2CO3. Subsequent condensation of (III) with ethylene glycol under Mitsunobu conditions afforded (hydroxyethyl)ether (IV). Palladium-catalyzed coupling of (IV) with 3-chlorophenylboronic acid (V) gave rise to terphenyl derivative (VI). Amide (VII) was then obtained by treatment of ester (VI) with n-dodecylamine in the presence of butyllithium. Finally, alcohol (VII) oxidation using N-methylmorpholine-N-oxide and tetrapropylammonium perruthenate furnished the title carboxylic acid.
